Spectracide Weed Stop for Lawns Plus Crabgrass Killer, Ready-to-Use Formula, 1 Gallon

I just moved into a rental home where the previous owners did a terrible job with the lawn — weeds everywhere, front, side, and back. I started spraying this stuff and honestly didn't see anything happening for the first few days. In the backyard, between two trees, there's a big patch of poison ivy that looked like it owned the place. I soaked that whole area, really hit it hard, and after three days it still looked just as strong. At that point I figured the product didn't work. Then about a week later I went back there and everything I sprayed was completely dead — including that entire poison ivy patch. All the other weeds I hit were gone too. It works slow, but when it kicks in, it wipes everything out. And it seems safer on the grass. I already bought another bottle to keep going.
